Vendredi

Today, head out to Rock n Bowl to make the cops shine during Carnival,  head to Gentilly's Stallings Playground Pool for Adult Swim or head to Ogden After Hours, where there will be blues. On this day in Louisiana history, Hurricane Betsy made landfall (1965) and Neville Uncle Big Chief Jolly of the Wild Tchoupitoulas passed (1980). Keep today with these:

Krewes for Kops (Rock n Bowl, 7:00 p.m.) New Orleans' Mardi Gras royalty are gathering to raise money so the cops can be spotted amid all the flashing lights during parade season. The fundraiser is designed to help police buy reflective vests, and in turn make them even better at crowd control than they already are. Beer, wine, food, music, prizes, a silent auction and of course bowling are all on the itinerary. $40 admission at the door.

Jason Mraz (UNO Lakefront Arena, 7:00 PM) The soulful singer songwriter swings his Tour is a Four Letter Word through New Orleans. He may even rap a little. Christina Perri opens.

Ogden After Hours w/Watermelon Slim (Ogden Museum of Southern Art, 5:00 p.m.) As it does about once a month, the Ogden gets the blues for tonight's After Hours soiree. Hailing from Ontario, Canada, these days, Watermelon Slim may not seem like he's straight from the Hill Country. But he's got the stripped down, rough around the edges sound and odd way of holding a guitar that helps him live up to blues fans' Delta demands.

Lil Wayne & Same Ol 2 Step (Rock n. Bowl, 8:30 p.m.) Some may accuse him of trying to be like Mr. Carter, but this is no Cash Money Millionaire. But, Wayne Singleton is a prodigy in his field, and he's been known to be cause for some dancing. Rock 'n Bowl welcomes this Cajun Country accordionist to the stage for the weekly Zydeco Night.

Adult Swim (Stallings Playground Pool, 5 p.m. - 6 p.m.) Kick over the kids to get in the water at this pool located off Gentilly Blvd. at the corner of Grand Route St. John. NORD is offering water aerobics, as well as a great chance to get your feet wet without getting splashed. Plus, it ends so early there will be plenty of time to catch the Cartoon Network's event of the same time later in the evening.
